The Silvretta Alps are a mountain range of the Central Eastern Alps shared by Tirol and Graubünden. The Austrian states of Tirol and Vorarlberg are connected by a pass road, the majority of the peaks are elevated above three thousand metres and are surrounded by glaciers. Thus, the area is known as the Blue Silvretta. According to the Alpine Clubs, the Silvretta Alps are outlined from other groups by the borders, St. Gallenkirch The Silvretta Alps are surrounded by the Rätikon, Verwall. The Piz Buin is not the highest, but the most popular peak of the range and it can relatively easily be ascended from north or south through glaciers and stretches of easy climbing. The Silvretta is famous for its skiing especially its many backcountry skiing possibilities, in the 1920s Ernest Hemingway was staying in the region for a winter. Later, he wrote a couple of stories about his skiing experiences in the Silvretta. Some of these stories are to be found in A moveable feast.

Albula District was one of the eleven administrative districts in the canton of Graubünden in Switzerland. It had an area of 723.13 km² and had a population of 8,210 in 2015 and it was replaced with the Albula Region on 1 January 2017 as part of a reorganization of the Canton. Albula District consisted of four Kreise Alvaschein, Bergün and Surses, on 1 January 2015 the former municipalities of Alvaschein, Stierva, Alvaneu, Brienz/Brinzauls and Surava merged to form the new municipality of Albula/Alvra. On 1 January 2016 the former municipalities of Bivio, Marmorera, Riom-Parsonz, Savognin, the official languages of the district of Albula are German and Romansh. In the municipality of Bivio, Italian has given way to German as the language there
A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism and these forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, a few mountains are isolated summits, but most occur in huge mountain ranges. High elevations on mountains produce colder climates than at sea level and these colder climates strongly affect the ecosystems of mountains, different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m, there is no universally accepted definition of a mountain.
Elevation, relief, steepness and continuity have been used as criteria for defining a mountain, whether a landform is called a mountain may depend on local usage. The highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m, Mount Scott outside Lawton, Oklahoma is only 251 m from its base to its highest point. Whittows Dictionary of Physical Geography states Some authorities regard eminences above 600 metres as mountains, in addition, some definitions include a topographical prominence requirement, typically 100 or 500 feet. For a while, the US defined a mountain as being 1,000 feet or taller, any similar landform lower than this height was considered a hill. However, the United States Geological Survey concludes that these terms do not have technical definitions in the US, using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As a whole, 24% of the Earths land mass is mountainous, there are three main types of mountains, volcanic and block.
All three types are formed from plate tectonics, when portions of the Earths crust move, compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of the feature makes it either a hill or, if higher and steeper, major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate, at a depth of around 100 km, melting occurs in rock above the slab, and forms magma that reaches the surface. When the magma reaches the surface, it builds a volcanic mountain. Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines, the magma does not have to reach the surface in order to create a mountain, magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US
The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc, Mont Blanc spans the French–Italian border, and at 4,810 m is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres, the altitude and size of the range affects the climate in Europe, in the mountains precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as live in the higher peaks to elevations of 3,400 m. Evidence of human habitation in the Alps goes back to the Palaeolithic era, a mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established, Hannibal famously crossed the Alps with a herd of elephants, and the Romans had settlements in the region.
In 1800 Napoleon crossed one of the passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, in World War II, Adolf Hitler kept a base of operation in the Bavarian Alps throughout the war. The Alpine region has a cultural identity. The Winter Olympic Games have been hosted in the Swiss, French, at present, the region is home to 14 million people and has 120 million annual visitors. The English word Alps derives from the Latin Alpes, maurus Servius Honoratus, an ancient commentator of Virgil, says in his commentary that all high mountains are called Alpes by Celts. The term may be common to Italo-Celtic, because the Celtic languages have terms for high mountains derived from alp and this may be consistent with the theory that in Greek Alpes is a name of non-Indo-European origin. According to the Old English Dictionary, the Latin Alpes might possibly derive from a pre-Indo-European word *alb hill, Albania, a name not native to the region known as the country of Albania, has been used as a name for a number of mountainous areas across Europe.
In Roman times, Albania was a name for the eastern Caucasus, in modern languages the term alp, albe or alpe refers to a grazing pastures in the alpine regions below the glaciers, not the peaks. An alp refers to a mountain pasture where cows are taken to be grazed during the summer months and where hay barns can be found. The Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km arc from east to west and is 200 km in width, the mean height of the mountain peaks is 2.5 km. The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, the range continues onward toward Vienna and east to the Adriatic Sea and Slovenia. To the south it dips into northern Italy and to the north extends to the border of Bavaria in Germany
Canton of Bern
The canton of Bern is the second largest of the 26 Swiss cantons by both surface area and population. Located in west-central Switzerland, it borders the canton of Jura, to the west lie the canton of Neuchâtel, the canton of Fribourg and Vaud. To the south lies the canton of Valais, east of the canton of Bern lie the cantons of Uri, Obwalden and Aargau. The canton of Bern is bilingual and has a population of 1,017,483, as of 2007, the population included 119,930 foreigners. The cantonal capital, the capital of Switzerland, is Bern. Bern joined the Swiss Confederation in 1353 and was between 1803 and 1814 one of the six directorial cantons of the Napoleonic Swiss Confederation and these caves were used at various times during the last ice age. The first open-air settlement in the area is an upper paleolithic settlement at Moosbühl in Moosseedorf, during the warmer climate of the mesolithic period, increasing forest cover restricted the movement of hunters and gatherers. Their temporary settlements were built along lake and marsh edges, which remained free of trees due to fluctuations in water level, important mesolithic sites in the Canton are at Pieterlenmoos and Burgäschisee lake along with alpine valleys at Diemtig and Simmental.
During the neolithic period, there were a number of settlements on the shores of Lake Biel, several of these sites are part of the Prehistoric Pile dwellings around the Alps, a UNESCO World Heritage Site. One of the best explored neolithic sites is at Twann, in the Twannbach delta there were about 25 Cortaillod culture and Horgen culture villages that existed between 3800 and 2950 BC. One of the oldest examples of bread from Switzerland, a sourdough from 3560–3530 BC, simple copper objects were already in use in the 4th millennium BC, including a copper pin from Lattrigen from 3170 BC and a knife blade from Twann. Shortly before 2000 BC bronze production entered the area and brought about a surge in development, settlements began to spread into the pre-Alpine and Alpine areas. The area between Lake Thun and the Niedersimmental were densely settled, Late Bronze Age settlements along Lake Biel have yielded up a wealth of items. During the early Iron Age changes in climate forced them to settlements along many waterways and in the valley floors and move to the plateaus.
With increased trade contacts across the Alps, the influence of the Mediterranean grew in the area. Evidence of this include a hydria which was discovered in Grächwil. Burial rituals and social classes became more developed during this time, the so-called princely graves became more common, many of the burial mounds were over 30 m in diameter and 4 m high and richly outfitted with grave goods. In a grave mound in Bützberg the first burial in the mound was followed by burials
Bernina District is a former administrative district in the canton of Graubünden, Switzerland. It had an area of 237.2 km² and a population of 4,619 in 2015 and it was replaced with the Bernina Region on 1 January 2017 as part of a reorganization of the Canton. It is the most south-easterly district in Switzerland, being surrounded on three sides by Italy and is predominantly Italian-speaking, as of 2000, 91% of the population speak Italian, followed by German and Romansh. Bernina District consisted of two sub-districts and Poschiavo, each of which contains a single municipality of the same name, the official language of the district of Bernina is Italian
The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major mountain peaks, the following sortable table lists the Earths 40 most topographically isolated summits. The nearest peak to Germanys highest mountain, the 2, 962-metre-high Zugspitze, the distance between the Zugspitze and this contour is 25.8 km, the Zugspitze is thus the highest peak for a radius of 25.8 km around. Its isolation is thus 25.8 km, because there are no higher mountains than Mount Everest, it has no definitive isolation. Many sources list its isolation as the circumference of the earth over the poles or – questionably, after Mount Everest the Aconcagua, highest mountain of the American continents, has the greatest isolation of all mountains. There is no land for 16,534 kilometres when its height is first exceeded by Tirich Mir in the Hindu Kush.
Mont Blanc is the highest mountain of the Alps, the geographically nearest higher mountains are all in the Caucasus. The Kukurtlu, which rises near the Elbrus, is the peak for Mont Blanc. com Canadian Mountain Encyclopedia peakbagger. com peaklist. org peakware. com World Mountain Encyclopedia summitpost. org

GIS or geographic information system is a computer system that allows for visualizing, manipulating and storage of data with associated attributes. GIS offers better understanding of patterns and relationships of the landscape at different scales, tools inside the GIS allow for manipulation of data for spatial analysis or cartography. A topographical map is the type of map used to depict elevation. In a Geographic Information System, digital models are commonly used to represent the surface of a place. Digital terrain models are another way to represent terrain in GIS, USGS is developing a 3D Elevation Program to keep up with growing needs for high quality topographic data. 3DEP is a collection of enhanced elevation data in the form of high quality LiDAR data over the conterminous United States, there are three bare earth DEM layers in 3DEP which are nationally seamless at the resolution of 1/3,1, and 2 arcseconds. This map is derived from GTOPO30 data that describes the elevation of Earths terrain at intervals of 30 arcseconds and it uses color and shading instead of contour lines to indicate elevation.
Hypsography is the study of the distribution of elevations on the surface of the Earth, the term originates from the Greek word ὕψος hypsos meaning height. Most often it is used only in reference to elevation of land, related to the term hypsometry, the measurement of these elevations of a planets solid surface are taken relative to mean datum, except for Earth which is taken relative to the sea level. In the troposphere, temperatures decrease with altitude and this lapse rate is approximately 6.5 °C/km. S
